This is the famous & desirable US Navy Standard Diving Knife used in conjunction with the Mark V diving helmet. This example was made by Diving Equipment & Supply Company, aka DESCO.  
 
The knife is in like new condition and has never touched the water. The brass sheath is clearly stamped DESCO on the belt loop ring. A nice, consistent patina is present on the brass.  The knife blade, wood handle, leather strap, and brass hardware are essentially flawless. 

Please be aware that we will only ship the knife within the United States.
